Plant Deficiencies! Advice Needed

Hey guys,

I began my first grow 3 and abit weeks ago and things have been running pretty smooth. I've have no problems with the plants and they seem
to be looking quite healthy. That was until this morning when I checked them. On all 3 plants the leaves have dropped and there's even a small yellow patch on one of the plants I've just noticed. could this be due to lack of nutrition?? as they've been fed just water since they were planted as they were set in bio bizz all mix soil so I figured I wouldn't over feed them with nutrients. can anyone point me in the right direction of where I may be going wrong, i'm a newbie so to see this on your first grow is hellish..lol i've uploaded some pics so you can grasp what im talking about. a big thanks in advance.

They look fine to me.

I really don't see anything

thanks for the replies, they do look like they have dropped dramatically since I last checked them yesterday, could this be where they're getting bigger so the leaves become heavier? I was just a little shocked to see this lol also, what week is recommended to start feeding nutes? thanks again

Is this a little after the light turns on? My plants looked a lil droopy in the morning right after the light turned on, but they perk back up in a bit. Some of my vegetable plants do the same lol

this is true they can look a little droopy at lights out and on

ah yeah they had just had 6 hours of darkness. i hope that was the reason. they do look a little perkier. thanks for the help guys
